# activating the source button
########################

# In order for this button to work the course needs to have a link from 

#   myCourse/html/show-source.cgi   back to webwork2/htdocs/show-source.cgi

#   in the directory myCourse/html
#   execute the following command (you will need command line access to the server to do this)
#   ln -s /opt/webwork/webwork2/htdocs/show-source.cgi    show-source.cgi
#    
#   You need to make sure that the file webwork2/htdocs/show-source.cgi is executable by the 
#   apache webserver.  
#
#   To accomplish this you need to uncomment this line in webwork.apache2-config
#
#   ScriptAliasMatch /webwork2_course_files/([^/]*)/show-source.cgi/(.*) /opt/webwork/courses/$1/html/show-source.cgi/$2
#
#
#   The show-source.cgi script may also have to be customized to set $root to the webwork2 directory
